GEORGE L. WITSIL, OF {"I. LOUIS, MISSOURI, ASSIGNQR- TO HIM- SELF AND T. L. BATES, OF PHILADELPHIA, PENNSYLVANIA.

'nurnovnn APP ARATUS FOR CLEANING BAGS.

To all whmn it 'may concern:

Be it known that I, GEORGE L. W rrsin, ot'St. Louis, in the county of St. Louis, and State of Missouri, have invented anew and useful Improvement in'Apparatus for Cleansing Rags, pulp, Sto. and I do hereby declare that the following is a full, clear, and exact description ofthe same, reference being had to thel annexed thawings, making prut of this peciticatiom in whichure lis a perspective view, and

Figure 2, a sect-ion ofthe pump.

My improvements relate to the construction and arrangement of an apparatus for cleansing rags, pulp, clothes, Ste., so that by the use of two cistcrns, by the. alternate exhaustion ot' thc air from eacli,acu1re1it of hot water may be caused to i'low through the articles subjected t0 the treatment, seryinY to remove all soluble impurities contained therein.

The following description will enable persons skilled in the art to construct and apply my apparatus to use.

In the annexed drawings I have shown, at A and Bj two close tubs, or cisterns. of any form, and of any rcquired size.

These cisterns are connected by a pipe, G, leading from near the bottom of one to near the bottoni of the other.

This pipe is closed or opened by a stop-cock, I). placed therein.

The cistern A rests upon a furnace, of any convenient construction, represented at E, by means ot which the water in said cistern may be heated to any required temperature.

The eistern B is supported upon legs, F, Aor in any other convenient manner.

The cisterns are covered by covers, A and B', the joint being packed by felt, Indial rubber, or other snitable material, so as to be made air-tight.

The coveis may be held in place by bars, G, which are screwed down by thumb-screws, H, passing through lugs, so as to draw the covers closely upon the packing, and also to prevent the covers from being displaced when the water is ho't enough to generate steam of high pressure.

I is au air-pump7 of any ordinary construction, which may be. either attached to the pipe ou cistem B, above the stop-cock K, or to the pipe in the cover A', closed by a cap, L.

Two air-pumps may, ii' preferred, be used, one being.

pernianentiy attac-'ned 'to each of the cistems.

The operation of the apparatus is as follows:

The articles to he cleansed are to be placed in cistern B, and the water is poured into cistern A, and heated to thc required temperature. The stop-cock D being closed, the air should then be exhausted from cistern B, by operating the air-pump. The stop-cock D should then be opened, and the hot water will immediately rush from cistern A into cistern B, passing through the articles placed therein. The air-pump applied to the pipe .L should then be set in operation, and the air exhausted from cistern A. The pressure of air through the open pipe K will drire the water from the cisteru B, through the pipe O, into the cistern A, when thc stopcock D is again closed; and the air is exhausted from the cistern B, and the water again admitted.

By continuing this operation, the hot water is made to flow through the articles submitted to its action, until they are properly purified.

That- I cla-im as my invention, and desire to secure by Letters Patent, is.

An apparatus, for the uses speciiied, consisting,r ofthe cisterns, pipes, stop-cocks, and air-pumps, arranged for operation, substantially as set forth.

In testimony whereof, I have signed my naine to this specification, in the presence of two subscribing witnesses.
